You can turn the background music off during a follow along workout while still hearing the trainer's voice.
Open the workout video you want to follow.
Once the video starts playing, you’ll see the music note icon at the top of the screen.
Tap the music note icon in the upper-right corner of the video.
The background music will be muted, and you’ll continue hearing the trainer’s voice.
To turn the music back on, simply tap the music note icon again.
Note: Not all workouts include optional music. The music can only be muted when the music note icon appears on the workout video.
